Description Alexander Chuzhoy 2018-02-01 15:56:13 UTC 
Upon starting an overcloud deployment with ceph need to have a check that the Pgnum value can be satisfied.


Environment:

Currently it's possible to start a deployment with wrong Pgnum value.
Would be great to have an automatic check that the value can be satisfied by the setup.

Effectively, this can prevent https://bugzilla.redhat.com/show_bug.cgi?id=1539852#c7


Example for manually changing the value - include a yaml with:
parameter_defaults:
    CephPoolDefaultPgNum: 32
